- “Package 0” involves completing the three projects underway (two with the United Kingdom, IFA 2 and ElecLink, and one with Italy, the Savoy-Piedmont project);
- “Package 1” includes all interconnections considered “without regret,” meaning their justification has been proven no matter which energy mix scenario plays out (strengthening begun with Spain via the Bay of Biscay line, strengthening with Germany and Belgium, the cost of which is low relative to the benefits provided);
- “Package 2” grouping together all other interconnection projects that are “subject to conditions” that may be political in nature (outcome of Brexit and clarification of the United Kingdom’s status), economic (amount of European subsidies, change in energy landscapes that may or may not support a project’s benefits to society) or technical.
Since the Ten-Year Network Development Plan was published, construction has started on the Package 1 Avelin/Mastaing-Avelgem-Horta and Aubange phase-shift transformer interconnections. Uncertainty surrounding the Celtic project has been lifted after a European subsidy was granted: French and Irish regulators were able to reach an agreement in October 2019 on the cross-border division of project costs.
